[solved] v17 BUG Text clipped MarkUp

Hi,

congrats to the new release. Surely a lot of work was put into that.

Unfortunately, after installing the final version, it tool only 5 seconds to find the first bug:

I use task dialogs with XAML markup. In the new version, text is clipped in the middle of the sentence, the Verify check boxes are clpped in the middle of the sentence etc. I cannot ship my software with this bug, please respond swiftly.

The text clipped is:

<TextBlock TextWrapping='Wrap'>Reset only the options in this dialog.</TextBlock>

while the text

<TextBlock TextWrapping='Wrap'>Reset the options in this dialog and also all custom data settings I made for individual file formats.</TextBlock>

is displayed correctly. See:



The text in the upper row should read "Reset the options in this dialog."

Here is an example with a clipped Verify check box: It should read "Don't show this message again".

This problem is new to version 17.




The screen shots were taken on a standard 4K monitor with 3940 pixels horizontal resolution at 150% font-size scaling (Windows) and 144 DPI.

Please advice, I need to ship on Tuesday.

I have found out that this seems to be related to how you manage DPI awareness in your toolkit.

The CXTPDpi::Init() method gets called very early, by some static variables you fill.

You call GetDC(NULL) and calculate the screen DPI as 96.
But the monitor is actually using 144 DPI.

After I figured that, I placed a call to

XTPDpiHelper()->Invalidate();

in the constructor of CMainFrame. This causes the method

CXTPDpi::Init()

to be called again. And this time, the DC returned by GetDC(NULL) returns the correct 144 DPI. Seems to be a side-effect of XTP or MFC initialization.

This solves the problem with the clipped "Verify" texts in Task dialogs, but not the other problems.
The problem with the clipped text in tooltips is also not affected by this change.

I had so far no feedback on these issues.
I'm already preparing plan B, going back to XTP version 16. Too many issues with the 17 release, sorry.

The issue with truncated caption on backstagebuttons isn't fixed with v17.2

Just installed version 17.2.0.
This problem is not fixed.

The  task dialog still renders only

"Reset only the options in this"

when using

<TextBlock TextWrapping='Wrap'>Reset only the options in this dialog.</TextBlock>

as the source.


Monitor with 144 DPI setting, Windows 10.

Hi, Artem

I've made the patch, re-compiled XTP and the problem is gone.

Good job! Thank you very much.

Probably sometime mid July
